Rototilt® R4 is our tiltrotator designed for excavators weighing between 10-16 tonnes. The R4 is built to cope easily with the harsh environments and significant stresses it will be exposed to in your daily work. Despite its low weight and compact format, the R4 can handle breakout torques of up to 163 kNm. With Rototilt's worm gear you get a smoother experience with less friction. The R4 also has a rotation sensor in the end section, that provides more precise positioning with RPS. In addition, the R4 has a high-pressure seal and smart grease fittings and a lower radial bearings in bronze.
This tiltrotator also includes our other functions and properties. That includes an oil-filled rotor housing cast in a single piece for maximum lubrication, minimal wear and an extremely long service life. You'll gain access to even more benefits when combining this with our control systems, the QuickChange™ quick coupler system and the SecureLock™ safety solution.
